Abstract
In this paper, a design of broadband detectors utilizing two ultra-wideband transitions is described for the first time, and the implementation method and measurement results of the detectors are provided. Two ultra-wideband transitions are used for input/output matching circuits for the diode detectors. Two detectors have been implemented using general Schottky diodes and zero-bias Schottky diodes. With general Schottky diodes, the fabricated detector provides less than 10 dB return loss from 11 GHz to 20 GHz, and the detector sensitivity is 30 mV/mW. The detector with zero-bias Schottky diodes shows significantly higher detection sensitivity(300 mV/mW).
